Basic Info

What is Thiamethoxam?

Thiamethoxam is the ISO common name for a mixture of cis trans isomers used as a new nicotine based endogenous insecticide. It has broad-spectrum activity against various insects and can be used as a seed dressing agent.

Thiamethoxam is a broad-spectrum internally absorbing insecticide, which means it can be quickly absorbed by plants and transported to all parts of the plant, including pollen, where it plays a role in preventing insect feeding. Insects can be absorbed into the stomach after feeding or through direct contact (including through their tracheal system). This compound interferes with nicotinic acetylcholine receptors in the central nervous system, hindering information transmission between nerve cells, and ultimately causing muscle paralysis in insects.

Syngenta claims that thiacloprid enhances plant vitality by triggering physiological reactions within plants, which induces the expression of specific “functional proteins” involved in various stress defense mechanisms of plants, enabling them to better cope with harsh growth conditions, such as stress caused by “drought and high temperature”, low pH, high soil salinity, free radicals generated by ultraviolet radiation, toxicity levels of aluminum, pests, wind Damage caused by hail and virus invasion.

In 1991, Ciba Geigy’s chemists first prepared thiacloprid. S-methyl-N-nitro-isothiourea was treated with methylamine to obtain N-methylnitroguanidine. This intermediate is used for Mannich reaction with formaldehyde in formic acid to obtain 3-methyl-4-nitroimino-1,3,5-oxadiazine. In the final step, the heterocyclic ring is N-alkylated by the thiazole derivative, resulting in a mixture of E and Z isomers of the final product.

Thiamethoxam Uses

  1. Main features of thiamethoxam
    Thiamethoxam is the alternate- generation neonicotinoid germicide developed after imidacloprid. Compared with imidacloprid, it has a wider insecticidal diapason, better water solubility, longer duration and lower toxin. It has the advantages of wide insecticidal diapason, strong systemic immersion, good stability, long- lasting effect, accessible use, and low price. In product, in addition to being used for scattering, there are also these new exercises, which are more accessible to use and kill germicides. Insects work more.
  2. Leafage spray
    Thiamethoxam is a alternate- generation neonicotinoid germicide, generally used to control aphids, rice planthoppers, whitefly, thrips, flea beetles and other piercing and filing- stinking pests. In the early stage of pest circumstance, use 5- 6 grams of 70 thiamethoxam- pymetrozine water- dispersible grains, blend with 30 kg of water and spot unevenly, because it has good systemic parcels and certain permeability, it can snappily stop pests Feed, effectively control the continued detriment of pests.
  3. Seed treatment
    Thiamethoxam is a alternate- generation neonicotinoid germicide with strong systemic property, good water solubility and long- continuing effect. It can also be used for seed treatment and control of underground pests. Before wheat sowing, 35 thiamethoxam suspense seed coating agent can be used to dress the seeds at a rate of 1200, and also sow after drying, which can effectively control slaveys, dayworms, operative justices, cutworms, ground bees, Leek bees and other underground pests can also control aphids, thrips and other ground pests. The validity period can reach 6- 7 months.
  4. Soil treatment
    Because of its slow metabolism in shops and soil, thiamethoxam has a long- term natural exertion, good water solubility in soil, long- lasting effect, and can also be used to treat soil. Before or when wheat is sown, use 500 grams of 3 thiamethoxam grains per mu, mix it with wheat seeds and sow together, it can also effectively control slaveys, needleworms, operative justices and other underground pests, and can also treat seedlings Aphids in the early stage can last for further than 3 months.
  5. Root irrigation treatment
    Thiamethoxam has good water solubility and strong systemic immersion. After being absorbed by the root system, the medicine can be transmitted from the root to the aboveground part, killing aboveground and underground pests.
    In the original stage of garlic bees, use 300- 500 ml of 35 thiamethoxam suspending agent, combined with irrigation, to wash the roots, which can effectively help the detriment of garlic bees.

The Difference between Thiamethoxam and Imidacloprid

  1. Both imidacloprid and thiamethoxam have similar duration of systemic effect.
  2. The types of applications are different on different crops, and the duration of the same product on different crops is also different.
  3. Seed dressing with thiamethoxam and imidacloprid can stimulate the growth of the root system and can strengthen the seedlings in the early stage. It is good for the control of piercing-sucking pests on the ground, but it is about avoiding underground pests.
  4. The average recovery rate of thiamethoxam in wheat grains, plants and soil was 79.62%~94.70%, the relative standard deviation was 0.91%~6.56%, and the minimum detection amount was 5.0×10-8g. Wheat grains, plants And the lowest detection concentration in soil is 0.01mg·kg-.
  5. The detection method has good reproducibility, high accuracy and precision, and can meet the requirements of residue analysis of thiamethoxam in wheat and soil.
  6. 180kg of insecticide raw material with 97% content of thiamethoxam. Quality 100% imidacloprid raw material 199k.

Imidacloprid has a long-lasting effect and has a good control effect on piercing and sucking mouthparts pests. Seed dressing against aphids is the most obvious. It can effectively prevent wheat aphids, wireworms, cutworms and other underground pests and wheat powdery mildew, root rot, sheath blight, take-all and other diseases. Enhance the absorption capacity of ginger-inch nutrients; roots have many long fibrous roots, grip the dungeon, and resist lodging. Improve the quality, so that the wheat has a good appearance and a high selling price. Balance nutrition, promote roots and seedlings, increase tillering, enhance cold resistance, imidacloprid seed dressing can improve wheat yield and quality. Wheat production increased steadily. Less investment, high output.

Summary: Both have their own advantages, and the control effect of imidacloprid is better than that of thiamethoxam compared with seed dressing. According to the needs, choose the appropriate insecticide.
